Thresholding strategies

limits called strategies to those, where confidence is greater than 40%

Saving the results

Here we export the results of the analyzed Track Files into a data.frame, to analyse them further.

results = Rtrack::export_results(experiment)
datatable(results, rownames = FALSE, filter="top", options = list(pageLength = 5, scrollX=T) )

Boxplot explanation:
Middle line in box -> Median
Box -> shows middle 50% of data(Distance between 1. and 3. Quartil)
Whisker(vertikal lines) -> show upper/lower 25% of data w/o outliers
Points -> outlier

Strategies 1-5 are less hippocampus-dependent, ‘unspatial’ and therefore get strategy.class = 0. In contrast to that, strategies 6-9 are more hippocampus-dependent, ‘spatial’ and get strategy.class = 1 assigned.

All probabilities in the following codes relate to choosing strategy.class = 1.
